A new method of surface modification of TiO2 nanoparticles by surface-grafting L-lactic acid oligomer was developed. The surface-grafting reaction was evaluated by Fourier transformation infrared (FTIR) and thermal ...

the improvement of the physical properties of indium tin oxide (ito) layers is quite advantageous in photovoltaic applications. in this study the ito film is deposited by rf sputtering onto p-type crystalline silicon (c-si) with (100) orientation, multicrystalline silicon (mc-si), and glass substrates coated with zno and annealed in vacuum furnace at 400°c. electrical, optical, structural and m...

Poly (lactic-co-glycolic acid) (PLGA) is a kind of medical polymer material with good biodegradability and histocompatibility, which widely used in postoperative anti-adhesion materials. In this paper, PLGA microfiber membrane was successfully prepared poly(lactic-co-glycolic as the main by electrospinning technology. The surface morphology, wettability, dimensional stability mechanical propert...

We report chemical modification of self-assembled block copolymer thin films by ultraviolet light that enhances the block-selective affinity of organometallic precursors otherwise lacking preference for either copolymer block. Sequential precursor loading and reaction facilitate formation of zinc oxide, titanium dioxide, and aluminum oxide nanostructures within the polystyrene domains of both l...

Nanocomposite films of metal nitrides such as TiN/Si3N4, TiN/BN, and CrN/AlN have attracted substantial attention as coating materials for improving hardness and saving rare metals. It is difficult to prepare composite films consisting of nitride and oxide by conventional reactive sputtering methods. Nose et al. developed a differential pumping cosputtering (DPCS) system, which can fabricate di...

Well-ordered 3D mesoporous indium tin oxide (ITO) films obtained by a templated sol-gel route are discussed as conductive porous current collectors. This paper explores the use of such films modified by electrochemical deposition of zinc oxide (ZnO) on the pore walls to improve the electron transport in dye-sensitized solar cells (DSSCs). Mesoporous ITO film were dip-coated with pore sizes of 2...

Abstract Advanced antimicrobial biomaterials for wound healing applications are an active field of research their potential in addressing severe and infected wounds overcoming the threat resistance. Beta-glucans have been used preparation these materials bioactive properties, but very little progress has made so far producing biomedical devices entirely beta-glucans integration with effective a...

The study describes the synthesis and characterization of zinc(II) minoxidil nanocomposite (1). The reaction between zinc(II) acetate, minoxidil, {C9H15N5O=minoxidil=(2,4-diamino-6-piperidine-1-yl) pyrimidine N-oxide)} as a ligand and KI as bridging agent, in methanol at 60°C leads to the formation of nano-sized Zn(II) minoxidil nanocomposite, 1. Characterization of (1) was carried out by eleme...

The mechanical properties of a tissue engineering scaffold are particularly important when engineering soft tissues as it has been shown that mechanical stimulation during in vitro tissue development can modulate cell differentiation, increase extracellular matrix synthesis, and enhance the mechanical properties of cartilaginous, ligamentous, and smooth muscle containing tissues [1-5]. Unfortun...
